Crap. I can't seem to get it right. I'm 6/3"/175 40 chest and I just ordered a L in the most recent season, as the old L's were too big but the re-cut seemed to make them much shorter. But given your fit pic, it seems like my L is still going to be too big. I'm not trying to get super fitted (my Fisherman in M from last season is quite snug, and I'm happy to have a little more room) but I really don't want a Stark that's down to my ass and really loose in body.
Guess we'll just have to see when it gets here.
